When I use BSModalUpdateView, "Choose File" text is showing instead of image showing from imagefield

class MyModelForm(BSModalModelForm):
	class Meta:
		model = MyModel
		fields = '__all__'

class MyUpdateView(BSModalUpdateView):
	model = MyModel
	template_name = 'mytemplate.html'
	form_class = MyModelForm
	success_message = _(' form has been save successfully.')

	def get_form(self, form_class=None):
		form = super().get_form(form_class=None)
		form.fields['file_upload'].label = _("file_upload")
		return form
